# CARD_WriteAndVerifyEeprom

## C Specification

      #include <nitro/card.h>
      static inline BOOL CARD_WriteAndVerifyEeprom(
          u32              dst,
          const void      *src,
          u32              len );

## Description

This function writes data to an EEPROM device and compares the written data.

This function returns a value of TRUE if the process succeeds, and returns a value of FALSE if the process fails. To obtain the detailed result value when the process fails, call the `CARD_GetResultCode` function.

Before using this function, you must lock the access bus using the `CARD_LockBackup` function.

This function does not return control until the process is complete.

This function communicates internally with the IO processor via PXI. Note that the process will not be completed unless the PXI interrupt is enabled.

## Arguments

`src` | Transfer source memory address.
`dst` | Transfer destination EEPROM address.
`len` | Length of the transfer data in bytes.

## Return Values

The function returns a value of TRUE if the process completes successfully and the data matches. Otherwise, it returns a value of FALSE.
